GRAIN-ELEVATOR ATTACHMENT.

Application med September'1l, 1925-. 'Serial in. 55,743.

To all whom it may concern:

Be it known that I, HECTOR H. PARLIA- MENT, a citizenof the United States, residp ing at Henry, in the county of'Codington and State ofSouthDakota, have invented for expeditiously removing the grain which clogs and causes the discontinuance of the operation of the lifting leg. of the elevator."

As is well known, grain elevators are of a considerable height and include bins arranged oneabove the other. These bins are so elevated thatchutes can be opened out bins. In elevating the grain'up tothe bins lifting legs are employed anda leg extends from above a bin down to a pit! The leg at its upper end discharges into the bin. The wvorking floor of theelevatoris above the pit. Oftentimes the elevator man on the work floor neglects to watch thebin above filling and after the bin ,becomes filled, uno less the'operation of the lifting leg is disgrain thereby clogging it and which causes the belt to shift oifthe pulley which drives the belt in the leg. lVhenthe'legbecomes clogged, the operator has to go down into the pit and openup a little opening int-he bottom of the pit and manually remove the grain from the leg, and as the belt i's 'generally off when the leg is clogged, theweight of the grain causes the, precipitation thereof to the bottom of. the leg. Generally when a leg clogs there are about five orsix bushels of grain in it and which has to be removed.

andthe belt or belts with the cupsv or buckets thereon again positioned if the belt or belts is or are off the pulley or pulleys. The clogged grain, as before stated, is removed from the bottom of the leg manually by the operator by forming an opening .in the bot tom of the pit and pulling out the grain by venient and requires considerable time. To overcome the inconvenient manner of removing the cloggedgrain is the primary object of this invention and the, attachment therefrom and cars filled directly from: the I continued the lifting leg becomes full of the hand. This method is somewhat incon' as hereinafter set forth, can quickly remove: the clogged grain, elevate the vsame'to the into a conduit for the grain leading to the Further objects of the invention are to provide, .in' a manner as hereinafter set forth, an attachment-for grain elevators,

work floor and then'can be easily discharged whichis simple in its construction and ar- 'rangement, strong, durable, compact, thor'-- oughly eflicient in its use, readily installed ufactlire. V V I IVVith the foregoing and other ob'jects'i'n view, theinvention consists of the novel construction, combination and arrangement of parts, as more fully described hereinafter,

and illustrated in the accompanyingdrawings, which form apart of this application and which illustrates an embodiment of'the with respect'to the lifting leg of the eleva- "tor, and "comparativelyinexpensive to maninvention, but it is to be' understood; that.

Figure l is' a vertical sectional view, of

an attachment in accordance, with this in- -with of'the attachment in accordance with this invention, theattachment being shown Referring to the drawings detailJl denotes a work floor and 2; the pitof a grain elevator. Extending into the pit 2, as well as projecting above the work; floor, 1 is a grain'lifti'ngleg 3 of the ordinary construction, but which has one side' thereof, in

proximity to its lower end, formed with an opening 4 which provides a passage for the clogged grain when the latter is removed from the leg3 by an attachment in accordance with this invention. I

:An attachment for grain elevators, in

accordance with this invention, comprises a casing;'5 which gradually increases in Width from its lower toward its upper end and at its upper end is provided with a discharge spout 6. Journaled in the casing 5 at the top thereof is a manually driven shaft 7 operated through the medium of a detachable handle member 8. Fixed to the shaft 7 and operated thereby is a spur or sprocket wheel 9 for operating an endless conveyor or elevating belt 10 provided with cups or buckets 11.

The belt 10 travels over a spur or sprocket wheel 12 arranged at the lower end of a casing 5. Secured to the outer side, at the lower portion of the casing 5, as well as extending into the said casing is a bearing member 13, through which extends a shaft 1% having the wheel 12 fixed thereto. The shaft 14 is of a length to project through the opening 4 into the leg 3 at the lower end of the latter and said shaft 14 carries on its inner end a conveyor screw 15 .for conveying the clogged material from the lower portion of the leg 3 into the casing 5 s so that when the belt 10 is operated the cups or buckets 11 will elevate the grain and theelevated grain will be discharged through the spout 6.

The casing 5 is of a length to extend slightly above the floor 1 so that it can be conveniently operated when occasion requires. The inner side of the casing 5 is fixed to that side of the leg 3 which is pro vided with an opening 4. Attaching means, as indicated at 16 is provided for securing the casing 5 to the leg 3. The inner side of the casing 5, at the lower end thereof, is formed with an opening 17, in which operates a slide 18, for the purpose of closing the opening 4. The slide 18 is bifurcated so as to straddle the shaft 14. The slide 18 is operated through the medium of a shifting bar 19, which is formed with a right angularly disposed upper terminal portion 20 extending through a slot 21 formed in the outer side of the casing 5. The upper end 20 of the bar 19 is positioned in convenient reach of the operator. The upper end 20 of the bar 19 carries a clamping nut 22 for the purpose of fixedly securing the slide in closed or opened posi tion. Guides or keepers 23 are provided for the rod 19.

hen the leg 3 becomes clogged by the grain, the slide 18 is shifted to open the opening 4 and after being shifted is secured in shifted position. The operator then revolves the shaft 7, which causes the operation of the conveyor belt on the chain 10, and on the operation of the latter the shaft 14 is revolved causing the conveyor screw 15 to convey the clogged material from the lower portion of the leg 3 into the lower portion of the casing 5 and from the lower portion of the casing 5 the grain is conveyed to the upper end of the casing 5 and then discharged through the spout 6.

It is thought that the many advantages of an attachment for grain elevators, in accordance with this invention for the purpose set forth, can be readily understood. and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.

What I claim is 1. An attachment for the lifting leg of a grain elevator comprising a casing adapted to be secured to one side of said leg and having a discharge spout at its upper end, means for establishing communication between the lower end of the casing and the lower end of said leg, grain elevating means arranged within said casing, and means operated from said elevating means and extending into the lifting leg for conveying grain from the latter into the path of said elevating means.

2. An attachment for the lifting leg of a grain elevator to remove clogging grain from the said leg comprising a casing positioned at one side of and of less height than the height of the leg and provided at its upper portion with a discharge spout, means for establishing communication between the lower end of the casing and the lifting leg, an endless grain elevating means arranged within and extending from the lower to the upper portion of said casing, and means for conveying clogging grain from said leg into said casing and within the path of said grain elevating means.

3. An attachment for the lifting leg of V a grain elevator for removing clogging grain from the said leg comprising grain elevating means arranged at one side of the leg, and means operating in said leg for conveying the clogging grain therefrom into the path of said grain elevating means.

In testimony whereof, I afiix my signature hereto.
